Crossplatform 3d engine.
(work in progress)
Tempest is an open-source, simple, cross-platform graphics engine written in modern C++14.
Main idea behind this engine is to provide a low-level GPU-programming concepts, like Ubo, Vbo, Ssbo, in convenient C++ packaging, with RAII, types and templates.
### Features
* Multiplatform (Windows, Linux, 32bit and 64bit)
* Multibackend (Vulkan 1.0, DirectX12)
* Multithreaded command buffers and thread safety
* Build-in 2d graphics support
* Build-in UI library
### Examples
```c++
// offscreen render
VulkanApi api;
Device device(api);
static const Vertex vboData[3] = {{-1,-1},{1,-1},{1,1}};
static const uint16_t iboData[3] = {0,1,2};
auto vbo = device.vbo(vboData,3);
auto ibo = device.ibo(iboData,3);
auto vert = device.shader("shader/simple_test.vert.sprv");
auto frag = device.shader("shader/simple_test.frag.sprv");
auto pso = device.pipeline(Topology::Triangles,RenderState(),vert,frag);
auto tex = device.attachment(format,128,128);
auto cmd = device.commandBuffer();
{
auto enc = cmd.startEncoding(device);
enc.setFramebuffer({{tex,Vec4(0,0,1,1),Tempest::Preserve}});
enc.setUniforms(pso);
enc.draw(vbo,ibo);
}
auto sync = device.fence();
device.submit(cmd,sync);
sync.wait();
// save image to file
auto pm = device.readPixels(tex);
pm.save(outImg);
```
